Julo Mark Bakke <mbakke@cisco.com> on 30/03/2001 19:32:37 Please respond to Mark Bakke <mbakke@cisco.com> To: Julian Satran/Haifa/IBM@IBMIL cc: ips@ece.cmu.edu Subject: Re: frame formats Excellent. Which header digest positioning method will we choose? 1. Single header digest, after BHS and AHS 2. Two header digests, one for BHS, one for AHS 3. Single header digest for BHS; AHS is added to data digest Option 3 will not work well with iSCSI proxies and gateways that may change header information, but keep the data end-to-end. To me, that leaves option 1 and 2. So, which is easier, having a single header digest in a variable location, or having the potential for two header digests; one in a fixed location, and an optional one in a variable location? I don't believe that we will see AHS on most iSCSI PDUs, so is it OK to have a "slow path" for these? -- Mark julian_satran@il.ibm.com wrote: > > Dear colleagues, > > It look like Format-2 is selected by popular vote. > > Julo -- Mark A.
